New AMSOIL Diesel Oils are Ready

NEW AMSOIL SYNTHETIC DIESEL OILS:

GET READY FOR CHANGE

Diesel oil is undergoing a major change. The new API CK-4 and FA-4 diesel oil specifications are here, and an overhauled AMSOIL synthetic diesel oil lineup is on the way, bringing even better protection and performance with it.

New Specifications, New Diesel Oils

The new API CK-4 and FA-4 specifications focus on these six goals:

Reduced emissions

Improved fuel economy

Stronger oxidation stability

Better shear stability

Increased resistance to aeration

Improved wear protection

The new API CK-4 specification is designed for current model-year and older diesel engines and is backward-compatible with API CJ-4 (and prior) oils. Going forward, all applications calling for a diesel oil meeting API CJ-4 (and prior) specifications should use an API CK-4 diesel oil.

The new API FA-4 specification is designed to further improve fuel economy and reduce emissions. FA-4 oils are not backward-compatible and may only be used in certain 2017 and newer overthe-road trucks, when approved by the original equipment manufacturer (OEM).

AMSOIL Signature Series Max-Duty Synthetic Diesel Oil

Signature Series Max-Duty Synthetic Diesel Oil represents the top tier of AMSOIL protection and performance for diesel engines. Signature Series will be available in 5W-30, 0W-40, 5W-40 and 15W-40 viscosities.

Turbodiesel Pickups: 2X OEM recommendation, not to exceed 25,000 miles or one year, whichever comes first.

Gasoline Engines: 2X OEM recommendation, not to exceed 15,000 miles or one year, whichever comes first.

Drain intervals may be extended further with oil analysis.

AMSOIL Heavy-Duty Synthetic Diesel Oil

AMSOIL Heavy-Duty Synthetic Diesel Oil will provide outstanding protection and performance for customers seeking an upgrade over conventional and other synthetic diesel oils. AMSOIL Heavy-Duty Synthetic Diesel Oil will be available in 10W-30, 5W-40 and 15W-40 viscosities.

4X more engine protection**

Excellent opportunity for priceconscious customers to move up to AMSOIL quality

API Licensing

Unlike OE Diesel, new AMSOIL HeavyDuty Synthetic Diesel Oil will not be API-licensed. Our philosophy has always been to set a target for quality and formulate products that meet that target.

The API licensing system is a voluntary certification that only sets minimum quality standards. Because it is a standard, licensing limits the flexibility we need to quickly adopt new technologies that can improve protection. Our research indicates many diesel enthusiasts and people who depend on their diesel to make a living focus more on protection than on the API doughnut. We are in that camp.

That is why we use specifications like CK-4 as the minimum and engineer protection into our products that goes beyond API standards. We want to give customers the most protection we can, and sometimes that requires opting out of a licensing program. Diesel customers can rest assured their equipment is protected, and we back them up with our warranty.

Pricing

The prices for the new diesel oil lineup will match the previous lineup. Meanwhile we expect the competition early on to increase prices around 15%.

Outstanding Protection for Ford* Power Stroke* Engines

Ford Motor Company recently released its position on the upcoming new API CK-4 and FA-4 diesel oil specifications, claiming it will only recommend diesel oils that meet the Ford WSS-M2C171-F1 specification or oils formulated specifically for the previous API CJ-4 specification.

Questions have arisen regarding why Ford would condemn use of CK-4 and FA-4 products in its Power Stroke engines. According to Ford Service Lubricant Technical Expert Ron Romano, “6.7L engines tested on CK-4 and FA-4 formulations had experienced valve train wear not encountered with CJ-4 formulations.” The CJ-4 formulations contained more than 1,000 parts per million phosphorus, an effective antiwear ingredient, while some CK-4 and FA-4 formulations were below that threshold. As a result, Ford declared that it has wear concerns about the use of CK-4 and FA-4 formulations with less than 1,000 ppm phosphorus in new and older Ford engines.

With the exception of AMSOIL Signature Series 5W-30 Max-Duty Synthetic Diesel Oil, all the new AMSOIL diesel oils provide boosted levels of phosphorus, are recommended for the Ford 6.7L engine and will carry the Ford WSS-M2C171-F1 specification. We have no concerns whatsoever that new Signature Series 5W-30 Diesel Oil will meet the wear protection requirements for the Ford 6.7L engine; however, we are choosing not to include the Ford WSS-M2C171-F1 specification and the 6.7L engine application on this product. Ford has identified a minimum phosphorus level, and Signature Series 5W-30 is below that minimum. Once the 6.7L engine test becomes available (today, it is not yet ready), we will demonstrate the superior wear protection of Signature Series 5W-30 in the Ford 6.7L engine. AMSOIL Dealers and customers can be well-assured that all Ford Power Stroke engines, no matter the model year, are well-protected when using AMSOIL synthetic diesel oils.

Specifications

The new lineup of AMSOIL synthetic diesel oils will be formulated to meet a broad range of industry and OEM specifications. They may be used in applications that require any of the following specifications:
